We investigate surrogate-assisted strategies for global derivative-free optimization using the mesh adaptive direct search MADS blackbox optimization algorit...
BibTeX referenceThe contribution of mathematical models to climate policy design: A researcher's perspective
Energy and the environment are closely interconnected. In particular, energy-related carbon dioxide emissions are major contributors to climate change. To an...
BibTeX reference
The classical p-median problem assumes that service to customers is always provided by the closest facility, while in practice, customers often interact for...
BibTeX referenceThe role of bioenergy in low-carbon energy transition scenarios: A case study for Quebec (Canada)
The Canadian province of Quebec has set for 2030 a greenhouse gas (GHG) emission reduction target of 37.5% below 1990 levels. Meeting such a reduction targ...
BibTeX reference
We propose a factorization-free method for equality-constrained optimization based on a problem in which all constraints are systematically regularized. ...
BibTeX referenceStabilized optimization via an NCL algorithm
For optimization problems involving many nonlinear inequality constraints, we extend the bound-constrained (BCL) and linearly-constrained (LCL) augmented-La...
BibTeX reference
In this paper we consider a version of the capacitated vehicle routing problem (CVRP) where travel times are assumed to be uncertain and statistically corre...
BibTeX reference
Within state-of-the-art optimization solvers such as IBM--CPLEX the ability to solve both convex and nonconvex Mixed-Integer Quadratic Programming (MIQP) pro...
BibTeX referenceBrand imitation: A dynamic-game approach
Brand imitation is a common practice that can take different forms, i.e., legal copying, as in the case of clones and knockoffs, or illegal, in the case of...

Signatories of the Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC) are exploring avenues to drastically abate their ...
BibTeX reference
The multiple depot vehicle scheduling problem (MDVSP) has been widely studied in the context of public transit systems. It consists of building vehicle sched...

Let \(G\)
be a graph of order \(n\)
. The energy \(\mathcal{E}(G)\)
of a simple graph \(G\)
is the sum of
absolute values of the eigenvalues of its ...
Despite the lack of theoretical and practical convergence support, the Nelder-Mead (NM) algorithm is widely used to solve unconstrained optimization proble...
